V i `My invention relates tofthe combinati-'on of'ahol- .l .lowed eccentric'iitted into the Vlock-case, and a Vhub i and latch slidngwithinvsaid'lock-case, in such a mannermthat the` said eccentric-,shallpermit t-he sliding of the latchtoclear its head from the case, for reversing,

thelturnng of the eccentricwith its long reach to the rear; bringing all thepieces ,into place, with the spindle-seat inthe eccentric and hub in line, the application `ofthe spindle, when` the lockis` uscd`,xobviating i all dangenofbreakage or disarrangernent.

.. The lock being complete, in order to reverse-the latch the eccentric aniust be turned with'its long reach to the front, the latch c will spring forward, carrying with it the the hub b and 'eein'g'the'swivelliead (I, which may then be reversed, the turning of the eccentric a, with its long reach to the rear, bringing all back to their place.

I am aware that a sliding hub has been before combined with a s\`vivelheaded latch, the hub'and latch fbeing retained in theirnorinal position, and controlled Witnesses y J oHNI W. GALMER, DANL. KINZER.
